Inner Barrel Prometheus EG 6.03 G&G ARP9/ARP556 128 mm
Direct leverbaar
Looking for an upgrade for your G&G ARP9 or ARP556? This Prometheus EG inner barrel builds on the proven barrel design of Tokyo Marui. With an inner diameter of 6.03 mm and particularly tight tolerances (+/- 0.01 mm), quality BBs get a neat fit in the barrel. The result: minimal pressure loss, even sealing around the BB and therefore accurate shot grouping. The outer diameter is 8.5 mm.
For the construction, sturdy, high-quality stainless steel was chosen. This causes this barrel to deform much slower than a standard one and can handle a lot. Among shooters, a Prometheus inner barrel is a trusted choice, with gains on multiple fronts:
- More accurate
- More robust
